IMPROVEMENT IN OPEN-FRONT HEATlNG-STOVES.

Specification forming part of Letters Patent No. 93,198, dated July 17,1677 application filed May 12, 1877.

I To all whom it may concern improved heating-stove that combines thecheerfulness and advantages of the open grate with the economicalfeatures of the common heating-stoves, and which provides, also, acontinuous and conveniently-regulated supply of pure heated air, actingas a ventilator and dust-escape in all the seasons.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

In the drawing, A represents the outer rectangular casing of ourimproved heatingstove, which is provided at the open front part with agrate, B, of the customary construction.

The fire in the grate is to be surrounded by four tiles, 0, which areplaced in outwardlyinclined or flaring position, so as to throw the heatforward by reflection. ported by a closely-fitting iron jacket, which iscast with a dust-flue, D, that is connected with a central bottomaperture, a, below the tiles, so as to conduct off all the dust in theroom, and act also, to some extent, as a ventilating-flue. The tiles areset loosely in the jacket, which is connected with the front, the frontbeing formed with a view to prevent the gas from escaping forward intothe room.

The exit-collar A is joined directly to the fire-box, which is superiorto the common construction, in which the collaris joined to the topplate at some distance above the throat leading from the fire-chamber,thus having to The tiles are sup pass through a large chamber of airwithout flue or collar to-conduct the discharge, which is objectionable.

The entrance-opening of the exit-pipe A and theupper end of the forwardinclined tile 0 are rounded off to admit the free exit of the smoke andgases into the pipe and chimney.

The open fire-place is surrounded by th casing A and closed by a topshelf, A, which form, together, a large air-chamber around the back,top, and sides of the fire-place. The air is introduced into thischamber, through bottom openings b, by means of a pipe or box beneaththe floor, from the outside of the house, being then heated up in theair-chamber, and thrown into the room by openings d at the top'partofthe casing A.

The bottom entrance and top exit openings are opened or closed byregistering devices 0, by which the admission of air is regulated. Thebottom registers are operated by rods c, passing up through theair-chamber and out through the top shelf. The air is warmed up in thisair-chamber and supplied in a pure state to the room.

The front of the stove is provided with a folding door or "shie1d, E,that is hinged to the face-plate, and stored away by its own weight in arecess, E{, of the face-plate, hanging down from the same, as shown inFig. 2,

when the fire is to be started. The face-plate beneath door or shield Ecatches all smoke and gas and conducts the same ofi through theexit-pipe A The stove rests on the floor and against the wall with orwithout feet, the outer.shell never becoming heated to such an extent astobe dangerous. If feet are used, they may be made of cylindrical form,and wide enough to correspond with the bottom apertures, so as toconduct the air.

The stove economizes heat and fuel, ventilates without introducing coldair, draws ofi the dust, so as to provide a purer air in the room,andadmits a quick fire at any time, without blowers, by the foldingshield.

The stove can be made ornamental in aprrron.
